SHEARS.

SPECIFICATION forming part of Letters Patent No. 240,884, dated May 3,1881.

Application filed March 5, 1881.

To all whom it may concern:

Be it known that I, JOSEPH W. CALEF, of North Easton, in the county ofBristol and State of Massachusetts, have invented certain new andusefulImprovements in Shears; and

I do hereby declare that the following is a full,

clear, and exact description of the'invention,

which will enable others skilled in the art to which it appertains tomake and use the same,

1 0 reference being bad to the accompanying drawings, which form a partof this specification, and in which- Figure 1 is an end or edge view.Fig. 2 is a sectional view; and Fig. 3 is a perspective view of thesliding cutter jaw or blade with its link, showing also the upper partof the lever or handle with which it is connected.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to hand-shears for cutting sheet metal orother tough material; and it consists in the improved construction andcombination of parts as hereinafter more fully described, whereby theshears are adapted to cut through the sheet metal or other materialoperated upon with comparativelylittle expenditure of power.

In the annexed drawings,Aand B represent the jaws or cutters of myimproved shears, the

base A of one of which has a chamber, a, open at both ends and at thetop and bottom, and reeessedor grooved longitudinally, as shown at b, toform ways for the shank or base B of the slidingjawB, which is insertedinto and works 3 5 in the chamber a.

At the inner end of the base Bthat is, the end opposite to its j aw B-ispivoted, in a downward-projectin g stud, d, a link or arm, 0, whichextends back under the base, and is pivoted at its other endin the uppercorner of the lever or handle D, which is cut out or recessed, as

(ModeL) shown at], to receive it. That part of lever D D which extendsinto the chambered base A is flattened and made with a shoulder orprojecti0n,g,opposite to its recessed partf, through which the fulcrumpin or boltE is inserted. The jaw A and its cham bered base A are in onepiece with the handle F.

Bythe construction and combination of the jaw B with its shank or baseB, rearwardly-ex- 5o tending link 0, and lever D D, all these parts,when properly connected, may be inserted and fulcrumed into thechambered base A of the oppositejaw, the handle D working on the sameside as the jaw B, which it operates, so that all that remains tocomplete thetool is toinsert the fulcrum pin or bolt E.

From the foregoing description, taken in connection with thedrawings,the operation of my improved shears will readily be understood,and requires no further explanation.

I claim and desire to secure by Letters Patent of the United States Asan improvement in shears, the cuttergjaw B, having the base B, providedat itsiuner end with the link 0, in combination with the flattened leverD D having recess fand perforated shoulder g, and the jaw A, constructedwith the chambered base A, having side grooves or recesses b, and handleF, said lever D D having its fulcrum upon the pin or bolt E, insertedthrough its perforated shoulder g, substantially as and for the purposeherein shown and specified.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

JOSEPH W. (JALEF.
